ELECTROLYTE ANALYSIS APPARATUS AND ANALYSIS METHOD

WIPO Patent Application WO/2023/013222

A1

Provided is an electrolyte analysis apparatus which is intended to measure the concentration of ions in a liquid and is equipped with an electrolyte analysis unit including an ion-selective electrode to be used for the measurement of a specific ion and a reference electrode, a diluent supply unit for supplying a diluent for diluting a reagent or a specimen, and a control device, in which the control device measures each of diluted reagents which are produced by diluting a reagent having a known concentration with the diluent and have a plurality of different concentrations and in each of which the concentration of a specific ion is known, and then the control device performs a water quality determination processing with respect to the diluted solutions on the basis of slopes obtained from results of the measurement. It becomes possible to reduce the burden on the measurement while preventing the deterioration in accuracy of results of the measurement.
